Today’s frenetic information landscape is making our brains busier than ever: the information triage that our over-burdened brains must constantly perform naturally drains huge amounts of energy. Constant multitasking also drains energy… notes neuroscientist Daniel Levitin, overstimulates and stresses our brains:
In addition to causing cognitive dizziness, this indistinguishable array of information erodes our ability to distinguish between the trivial and the truly important. Over time we come to value information more for its spectacle—infotainment—than for the complex realities it signifies. Our news feeds are the amusement parks, penny arcades, and vaudeville stages of the digital era.
Ironically, as much as the information age (and its “global village”) promises to broaden our horizons and create healthy, integrated, well-informed global citizens, in reality it has had the opposite effect. The hyper-connection and over-awareness of a space-conquered world renders us fragmented and disconnected from place—the local contexts where we can know and be known and effect change to the greatest degree.
After the telegraph, Postman argues, “Everything became everyone’s business. For the first time, we were sent information which answered no question we had asked, and which, in any case, did not permit the right to reply.” Social media, of course, gives us permission to “reply”—but to what end? We may have a sense that our participation is meaningful action, that it is doing something, but more often than not we are only adding to the noise, getting needlessly angry, and contributing more irrelevant information to our already overloaded, exhausted brains.
Indeed, the stress of having to actively sift through viewing options tends to make us more passive, with little capacity for what Tony Reinke calls “spectacle resistance”: “Our lazy eyes and incurious gaze are happily fed by the spectacle makers. We no longer seek out new spectacles; new spectacles seek us out.”
Asking the brain to shift attention from one activity to another causes the prefrontal cortex and striatum to burn up oxygenated glucose, the same fuel they need to stay on task. And the kind of rapid, continual shifting we do with multitasking causes the brain to burn through fuel so quickly that we feel exhausted and disoriented after even a short time. We’ve literally depleted the nutrients in our brain. This leads to compromises in both cognitive and physical performance. Among other things, repeated task switching leads to anxiety, which raises levels of the stress hormone cortisol in the brain, which in turn can lead to aggressive and impulsive behaviour.
